OBJECT OF THE INVENTION

As stated in the title of this specification, the following invention relates to a border protector fence system, being of special utility for the assembly thereof in the protection of border zones, with the aim of being able to quickly detect any attempt at access via the fence system.

Likewise, an important aim of the invention is to permit a system to be had which is reliable and at the same time prevents any kind of accident in the event of an attempt at access.

FIELD OF APPLICATION

This specification describes a protector fence system, which of special utility for the assembly thereof in the protection of border zones.

PRIOR ART OF THE INVENTION

Conventionally, among systems used in border fences having the aim of preventing passage from one country to another, we can consider the system which consists of a pair of fences, parallel to each other, installed along the length of the zone to protect and whose fences are made up of support profiles between which is arranged a metal net.

Likewise, in a first practical embodiment, the upper part of the support profiles can end in at least one inclined section, with various rows of barbed wire being provided between those inclined sections.

In a second practical embodiment, the support profiles can end in two inclined sections, towards both sides, with various rows of barbed wire being able to be provided between them, while in their central upper part, between the inclined sections, which define a “V” shape in space, a spiral roll of barbed wire can be laid.

In this way, it is possible to position a ladder or other similar elements on top of the barbed wire arranged between the inclined sections in which the support profiles end with the aim of being able to access the upper part of the fence and, by means of laying a protector element on top of the barbed wire, such as a simple piece of cardboard, with the aim of preventing cuts, one can overcome the fence.

Equally, in relation to the internal face of the first protector fence, one or more rolls of barbed wire can be positioned, these rolls being able to take on different arrangements.

The barbed wire defining the spiral roll can present different forms of blades.

This configuration presents the drawback that, in addition to not being infallible, anyone who tries to “clear” the described protector fence could suffer serious accidents, mainly as a consequence of severe cuts.

DESCRIPTION OF THE INVENTION

The present specification describes a border protector fence system, being of special utility for the assembly thereof in the protection of border zones, in such a way that the system comprises:

-   -   a first fence consisting of some profiles secured in an inclined         position, ending in at least one hinged spring, among which         profiles some steel stays and a metal net are arranged;     -   a second fence consisting of some profiles secured in a vertical         position, with some steel stays and a metal net being arranged         among them;     -   some profiles arranged between the first and second fence, of         less height than the profiles of the first and second fence,         with a diversity of intersecting steel stays being provided         between the intermediate profiles and the first and second         fence;     -   means of alarm mounted in relation to the second fence,         associated with the structure of the first fence and with the         diversity of intersecting steel stays arranged between the first         and second fence; and     -   some ducts for a fluid mounted in relation to the second fence         provided with some outlet mouths under pressure towards the zone         of the intersecting stays.

The profiles relative to the first fence will be secured with an inclination towards the side where access is possible, presenting an inclination of approximately 75° with the ground.

Likewise, in a preferred embodiment, the profiles secured in an inclined position relative to the first fence present a general cross-section in the form of a double “T”, with a series of holes in its core at different heights, for the passage and positioning of the steel stays or cables, in such a way that the lattice of stays or cables between the profiles relative to the first fence stiffen the latter and prevent passage in conjunction with the metal net.

Equally, the profiles secured in an inclined position relative to the first fence present a pair of hinged spring elements in their upper part, mounted in proximity and consisting of a body with a series of annular pieces for the passage of some steel stays.

Moreover, a first hinged spring element, relative to the profiles constituting the first fence, is mounted at its free end with an inclination greater than that of the actual profile, while the second hinged spring element, mounted at a slightly lower position, has the same inclination as the actual profile.

So, in the event of an attempt to position any support such as a ladder, in order to thereby gain access to the upper part of the first fence, the actual action of its weight on the stays or cables, arranged in the highest position and associated with the hinged spring elements, will cause them to rotate downwards, thus preventing access.

From their original rest position, the hinged spring elements have a limited angle of rotation, downwards, depending on the desired angle.

Moreover, the means of alarm mounted in relation to the second fence consist of at least one perimetric system defined by a diversity of stays, which cover the entire perimeter, to which an optical fibre is incorporated with an emitter and a receiver, being associated with the structure of the first fence and/or with the structure of steel stays or cables existing between the first and second fence.

In this way, in a practical embodiment of the invention, the means of alarm mounted in relation to the second fence can consist of two perimetric alarm systems, a first perimetric system being defined by a diversity of stays, which cover the entire perimeter, to which is incorporated an optical fibre with an emitter and receiver, to which stays are joined a series of stays which are in turn joined to the structure of the first fence.

The second means of alarm mounted in relation to the second fence will consist of a second perimetric system, defined by a diversity of stays, which cover the entire perimeter, to which is incorporated an optical fibre with an emitter and receiver, to which stays are joined a series of stays which are in turn joined to the structure of intersecting stays existing between the first and second fence.

So, at the moment the structure of the first fence is acted upon, the stays joined to that structure associated with the first means of alarm will provoke the immediate activation of the latter, permitting action to be taken instantly, knowing the exact place of the attempt at access, while if anyone overcomes the first fence they will find themselves in the zone relative to the lattice of stays as far as the first fence and at the moment any of the lattice of stays is touched, the second means of alarm will be activated.

Finally, the system incorporates some ducts for a fluid (water) mounted in relation to the second fence provided with some outlet mouths under pressure towards the zone of intersecting stays, in such a way that the water can incorporate an irritant liquid which affects the eyes though without causing any physical harm.

In short, the aim is to obtain a reliable fence system which prevents access via it and at the same time permits the retention of persons without causing any physical harm.

In order to complement the description that is going to be made, and with the aim of aiding a better understanding of the characteristics of the invention, this specification is accompanied by a set of drawings containing figures which, on an illustrative rather than limiting basis, the most characteristic details of the invention are represented.

BRIEF DESCRIPTION OF THE DESIGNS

FIG. 1. Shows a side elevation view of the border protector fence system, where it can be seen how the system consists of a first fence and a second fence between which are some profiles of lesser height and a series of intersecting steel stays.

FIG. 2. Shows a front view of the border protector fence system, where it can be seen how the profiles relative to the first fence end in some hinged spring elements.

DESCRIPTION OF A PREFERRED EMBODIMENT

With the commented figures in view and in accordance with the numbering adopted, we can see how the border protector fence system 1 comprises a first fence 2 consisting of some profiles 3 secured in an inclined position, ending in at least one hinged spring element, presenting a series of steel stays 4 and a metal net between the profiles 3, and a second fence 6, parallel to the first fence 2, consisting of some profiles 7 secured in the vertical position, presenting a metal net between the profiles 7, with some profiles 8 of less height being arranged between the first fence 2 and the second fence 6, between which profiles 8 and the profiles 3 and 7 relative to the first and second fence there is a diversity of intersecting stays 9.

The border protector fence system 1 is installed close to the conventional fence 10, with a space 12 remaining between them in such a way that the already existing conventional fence consists of some profiles 11 between which is a metal net 5, this metal net 5 being conventional and similar to that mounted between the profiles 3 of the first fence 2 and between the profiles 7 of the second fence 6.

In this way, between the profiles 3 of general cross-section in the form of a double “T”, relative to the first fence 2, secured in an inclined position, approximately 75°, a series of steel stays 4 is provided passing through a series of holes made in its core at different heights, which stays 4 will act as strengthening elements for the metal net arranged between the profiles 3.

Likewise, in a preferred embodiment of the invention, the profiles 3 secured in an inclined position relative the first fence 2 present a pair of hinged spring elements 13 and 14 in their upper part, mounted in proximity and consisting of a body with a series of annular pieces 15 for the passage of some steel stays 16.

In this way, we can see in FIG. 1 of the designs how a first hinged spring element 14, relative to the profiles 3 constituting the first fence 2, is mounted at its free end with an inclination greater than that of the actual profile 3, while the second hinged spring element 13, mounted at a slightly lower position, has the same inclination as the actual profile 3.

Moreover, the system 1 incorporates means of alarm mounted in relation to the second fence 6, which means of alarm consist of at least one perimetric system defined by a diversity of stays, which cover the entire perimeter, to which an optical fibre is incorporated with an emitter and a receiver.

In this way, in a preferred embodiment the system will incorporate a pair of alarm means, each one of them consisting of a diversity of stays 17 and 18 with an emitter 24 and a receiver 25 each.

So, a first means of alarm defined by the diversity of stays 17 will be associated with the structure of the second fence 2 and/or with the structure of intersecting stays 9 existing between the first and the second fence, in such a way that, in order to achieve this, the stays 17 will be joined to a series of stays 19 and 20 which are in turn joined to elements constituting the structure of the system. One can thus see how the stays 20 are associated with the spring elements 13 which are in turn associated via some stays 22 with the spring elements 14.

The second means of alarm mounted in relation to the second fence 6 is defined by a second perimetric system, defined by a diversity of stays 18, which cover the entire perimeter, to which is incorporated an optical fibre with an emitter 24 and receiver 25, to which stays 18 are joined a series of stays 21 which are in turn joined to the structure of intersecting stays 9 existing between the first and the second fence.

Finally, the fence system 1 incorporates some ducts 23 for a fluid mounted in relation to the second fence 6 provided with some outlet mouths under pressure towards the zone of intersecting stays 9, said fluid being able to incorporate an irritant liquid.

In this way, the aim is so that, at the moment any component of the structure of the system is acted upon, an alarm is activated permitting action to be taken very quickly.

So, if, for example, someone attempts to gain access via the first fence 2 and wishes to do so using a ladder, when this is rested on an hinged spring element 13 or 14 its rotation will be provoked, causing displacement of the stay 20 or 22, which will in turn act on the alarm means 17 activating the alarm. Equally, if someone acts on the metal net arranged on the profiles 3 of the first fence 2, this will cause the stay 19 to act on the alarm means 17.

Likewise, if any intruder succeeds in overcoming the first fence 2 they would run up against the lattice of intersecting stays 9 which, as well as hindering their advance, would provoke the activation of the alarm means 17 and 18 since said lattice of stays 9 is associated with the first and/or second means of alarm 17 and 18.
